We added a new Yorkie to our family. Our 4 yr old Maggie, needed a friend to play with. So, now we have Molly. Molly is 4 months old, has a great deal of energy, eats everything (including her poo). The only thing that she doesn't do, is BARK. From day one, she makes a tiny noise like a baby raccoon. Never has she barked. We have two heelers and the two Yorkies. When the other furkids kick up a barking storm, Molly just watches. She hears just fine, and comes when called. Does anybody have this concern? I don't want to call it a problem. Sometimes quiet is good. I'm just concerned.
